Have there been any reports on timing for Sandy Bridge iMacs? Seems like they should be out any minute now... Last front page update was 3 weeks ago, saying 4-6 weeks until release. Potential iMac Update to Sandy Bridge and Thunderbolt in 4-6 Weeks? I ask because the logic board on my 2008 iMac died today, right in the middle of work. Hoping I don't have to wait too long to replace it.
